` warms. (ol. i12- 266) Our invention relates to ka new form ,of reenforced hemstitching, aswell' as Ato the method lof producing the same. g y

Hemstitching lof. sheets, pillow'j'cases, and the like has long been`resortedto'finvorder to impart a pleasing appearance,totheffinished articles, However, the "disadvantage p hasjalways'been recognized that h'emstitchingas hithertopracticed has been quite 'delicate'a'nd fragile as compared to the fabric 'itselfof the article, so that often after but a comparatively fewwashings the article willbe'gin Vto tearjor rip Valong the line'of hemstitching. Y A i g Thus because of their lack of durability, hem- ]5 stitchedV articles have comeinto nowherenear the widespread use towhich they are entitled by virtue of their superior appearance. Only the relatively wealthy could afordttheirlusein quantity.

It has been recognized that if'onlyjitwere possible toy retain the pleasing appearance vof Vhemstitching, while increasing the durabilityfof the hernstitchedarticle, 'the kuseful range' of "hemstitching would increase materially." f V,

We have devised anew lmethod of reenforcing hernstitching, givin'gris'e Lto a product which While on its face side it has the appearance of ordinary hemstitching, at the same time it is provided in the rear of the hernstitching with a reenforcing backing and an extra row of hemming. In brief, to produce our reenforced article, a sucient number of threads of the lling are drawn to leave the space desired, this operation being performed on the usual machine. The hemstitching is then .carried out, preferably on a` machine, and whereas in the ordinary hemstitching the end of the hem or raw edge is turned in, is sewed, and both edges are bound to form the spoke of the hemstitching, all in one operation, in our case the end of the hein or raw edge is turned out, away from the region of hemstitching, leaving a free portion sufficient to overlap the spokes of the hemstitching. Thereafter, in a separate or second operation, this free end is folded in, or under, and is hemmed, thus providing a backing and a. reenforcing hem for the row of hemstitching.

An object of our invention, then, is to produce a new form of hemstitching.

Another object is to produce a new method of hemstitching.

Other objects and advantages will more fully appear in connection with the following description.

One at-present-preferred form of our invention tions' onja scale approximately twice that of Fig.. '1, showing two separate steps in the process of hemstitching, while Fig. 4 is an-end elevation of the sheet, on vthe same scale as Fig. l. rIn carrying out the process, a number of the threads ofthe filling of a sheet I or the like are pulled out inthe region 2 in any suitable manner,

as lbyone of the several'known machines adapted for-this purpose.

A hem is'next formed byv folding over the end of the sheet to form the two legs 3 and` 4, and

v'then' the raw edge 5 is folded outwardly. The 'hem thus will be seen to have an inner end, advl1j acent the body material, as well as an outermost,

freelend.V n l Ordinarily, as has been suggested in the first part of rthis description, the raw edge is turned under, or inwardly, the hembeing sewn, and both edges along the'region of pulling being bound t0 `fo`rm` the spokes of the 'hemstitching all in a single operation.

However, in our case, the folded-back edge 5 is gathered at 6, and by means of the usual binding Vstitching 1, is secured to the hemstitching, the

spokes of which are shown at 8.

The raw edge 5 is then folded down, as shown in Fig. 3, and the portion 9 thereof is folded in or under. The reenforcing or backing portion I0 of the raw edge 5 is designed to have sufficient length to overlap the spokes of the hernstitching.

The fold I I of the raw edge 5, joining the portions 9 and I0, now lies snugly against the body portion I of the sheet, and is now secured thereto as by a row of conventional stitching I2.

It is obvious from the foregoing that the backing Iil fully reinforces the hemstitching 8, while leaving its surface appearance substantially unchanged. At the same time, instead of the fragile hemstitching being called upon to withstand all the tensional strain when the sheet is stressed, which causes the normal hemstitching to rupture quickly, the stress will be distributed between the stitching 'I and the stitching I2, and as a matter of fact, the greater p-art o-f the stress will be taken up by the stitching I2.

As a typical instance, a pillow case hemstitched according to our process was laundered 35 times without apparent weakening of the hemstitching.

It will be seen then, that our invention comprises producing a reenforced hemstitched article, having a strengthening backing and a double row of hemstitching, by drawing the required threads from the filling, folding over a hem, folding the raw edge of the hem outwardly and backwardly, performing the hemstitching operation and then folding the raw Vedge downwardly andzinwardly, `to overlie the hemstitching, at which time the said raw edge is hemmed in place.

It will be readily understood that once *the broad aspects of our invention are disclosed, many modifications and adaptations will v'readily''occur to those skilled in the art, but all :falling within the scope of our invention. .Accordingly 'we-Tin tend that such invention-is .to be. limited-only by the scope of the appended claims.

We claim:

l. A new form of hernstitching, comprising a material having hemstitching therein, and*abacking formed on `said material inthe vrear of and extending across said hemstitch'ing and .constituting an integral part of `.said material.

-2. -A new form of hemstitching, comprising .a material havingr hemstitch-ing therein, a backing on' said material A.in the .rear of 'and extending :across said hernstitching, Athe said backing :hav-

ing a free end thereon, and a second-.row of. stitching securing the free'end .of -said backing to-said material. Y

Y3. ,VA new :form of -hemstitching, comprising a material .having `hem-stitching in one 4'i'.urfane thereof, ahem in said material andforminggpart thereof and disposed on one .sidefof said hemstitching and stitched thereto, and a free-edgefon said hem voverlapping Vthe rear of said fhemstitching `and reenforcin-g the same and-havingian end thereom and a row .of ystitcliingsecuring the `end 'of said free Vedge to the material. y

LV A new form of. hemstitching, comprising :a

material having hemstitching in one surface an end thereon. and a row of stitching securing the end of said free edge to the material, a gather being formed between the free edge and the body of the hem, and the said gather being stitched to the hemstitching along with the hem.

5. A method of producing reenforced herntitching, comprising folding one end of the maiterial onto .the body thereof to form a hem, turning the raw edge of the end of the material 1 `outwardly and away from the body material, hemstitching the body material at the inner end of the l'heni'anifunltlng the end of the hem to the body .imitexzial .turning .the-raw edge of the end of the .material iniwardly :in overlapping relation to the '.hng, :und .securing the end thus turned #to `'the body material.

`.6. .A method .of producing reenforced hemstitching comprising folding one end of the material mbo the body thereof to form a hem, turninga width iof the raw edge of the end of. the matei-laloitwardly 'and away from the body materia'l Asu'iiicient"tooverlap the hemstit'ching, hem- `stitching the body material at the inner end of thehem .andlxmtiglzhe end of fthe hem to the body material, .turning the raw edge of the end `of .the material'inwaidly 'in overlapping relation 4to lthelhemstltchin'g, securing the endthus .turned to .the body material.
